Description
Technical field
The utility model relates to a kind of reboiler, relates in particular to a kind of no benzene paint solvent reboiler.
Background technology
Along with China's rapid development of economy, industrial enterprise's pollution problem is more and more serious.For adding solvent in the production process of producing paint, these solvents generally all are employing toluene, dimethylbenzene, acetone, contain benzoline etc., it is very big to the production and the use toxicity of product of paint that these contain benzene solvent, had a strong impact on the healthy of worker, also polluted environment.And the appearance of not having the benzene paint solvent has replaced the key that the raw material that contains benzene is prevention benzene poisoning and environmental pollution, needing to use reboiler in the production of non-toluene solvent gasifies once more, and traditional reboiler is the shell and tube heat-exchange device at present, but because the corrosivity of no benzene paint solvent and heating high temperature make the service life of shell and tube heat-exchange device short, secondly, the problem that the shell and tube heat-exchange device occurs leaking has easily had a strong impact on normally carrying out of producing, and has also caused the generation of security incident.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of no benzene paint solvent reboiler is provided, and this reboiler long service life guarantees carrying out smoothly of safe in utilization and production.
For solving the problems of the technologies described above, the technical solution of the utility model is: no benzene paint solvent reboiler, comprise housing, be fixed with upper spacer and lower clapboard in the described housing, described upper spacer and lower clapboard are separated into epicoele with described housing, lumen and cavity of resorption, described reboiler also comprises heat-exchange device, described heat-exchange device comprises last solvent connected chamber that is arranged in the epicoele and the following solvent connected chamber that is arranged in the cavity of resorption, the described solvent connected chamber of going up is provided with the discharging opening that extends upward outside the housing, described solvent connected chamber down is provided with and extends the outer charging aperture of housing downwards, be sealed and installed with the heat-exchange tube with last solvent connected chamber and the connection of following solvent connected chamber between described upper spacer and the lower clapboard, the chamber wall of described lumen is provided with heat medium import and heat medium outlet.
As a kind of preferred scheme, the chamber wall of described cavity of resorption is provided with the safety return-flow mouth, is sealed and installed with the safety return-flow pipe with epicoele and cavity of resorption connection between described upper spacer and the lower clapboard.
After having adopted technique scheme, effect of the present utility model is: because no benzene paint solvent reboiler, comprise housing, be fixed with upper spacer and lower clapboard in the described housing, described upper spacer and lower clapboard are separated into epicoele with described housing, lumen and cavity of resorption, described reboiler also comprises heat-exchange device, described heat-exchange device comprises last solvent connected chamber that is arranged in the epicoele and the following solvent connected chamber that is arranged in the cavity of resorption, the described solvent connected chamber of going up is provided with the discharging opening that extends upward outside the housing, described solvent connected chamber down is provided with and extends the outer charging aperture of housing downwards, be sealed and installed with heat-exchange tube between described upper spacer and the lower clapboard with last solvent connected chamber and the connection of following solvent connected chamber, the chamber wall of described lumen is provided with heat medium import and heat medium outlet, feed heat medium to the heat medium import, feed liquid flux to charging aperture, liquid flux enters in the heat-exchange tube from following solvent connected chamber, because heat medium exists in the lumen, carry out heat exchange between liquid flux in the heat-exchange tube and the heat medium, thereby make the liquid flux gasification, and through last solvent connected chamber, discharge from discharging opening, because the position that sealing is installed between heat-exchange tube and last solvent connected chamber and the following solvent connected chamber lays respectively in epicoele and the cavity of resorption, directly directly do not contact with heat medium, and just the tube wall of heat-exchange tube directly contacts with heat medium, therefore, just improved the service life of heat-exchange tube, also reduced heat-exchange tube the probability generation that solvent leaks has taken place in the junction with last solvent connected chamber and following solvent connected chamber, prolong long service life, guaranteed carrying out smoothly of safe in utilization and production.
Because the chamber wall of described cavity of resorption is provided with the safety return-flow mouth, be sealed and installed with safety return-flow pipe between described upper spacer and the lower clapboard with epicoele and cavity of resorption connection, therefore, occur leaking to be back in the cavity of resorption and by the safety return-flow pipe and flow out in case position that sealing installs occurs between heat-exchange tube and last solvent connected chamber and the following solvent connected chamber, thereby avoid solvent to remain in the housing further corrosion housing for a long time from the safety return-flow mouth.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the structure cutaway view of the utility model embodiment;
In the accompanying drawing: 1. housing; 11. epicoele; 12. lumen; 13. cavity of resorption; 2. heat-exchange device; 21. following solvent connected chamber; 22. last solvent connected chamber; 23. discharging opening; 24. charging aperture; 25. heat-exchange tube 3. safety return-flow mouths; 4. heat medium import; 5. heat medium outlet; 6. upper spacer; 7. lower clapboard; 8. safety return-flow pipe.
The specific embodiment
A kind of no benzene paint solvent reboiler, as shown in drawings, it comprises housing 1, be fixed with upper spacer 6 and lower clapboard 7 in the described housing 1, described upper spacer 6 and lower clapboard 7 are separated into epicoele 11 with described housing 1, lumen 12 and cavity of resorption 13, described reboiler also comprises heat-exchange device 2, described heat-exchange device 2 comprises last solvent connected chamber 22 that is arranged in the epicoele 11 and the following solvent connected chamber 21 that is arranged in the cavity of resorption 13, the described solvent connected chamber 22 of going up is provided with the discharging opening 23 that extends upward outside the housing 1, described solvent connected chamber 21 down is provided with the charging aperture 24 that extends outside the housing 1 downwards, be sealed and installed with heat-exchange tube 25 between described upper spacer 6 and the lower clapboard 7 with last solvent connected chamber 22 and 21 connections of following solvent connected chamber, the two ends of described heat-exchange tube 25 are tightly connected with last solvent connected chamber 22 and following solvent connected chamber 21 respectively, described heat-exchange tube 25 runs through described upper spacer 6 and lower clapboard 7 and is provided with described upper spacer 6 and lower clapboard 7 sealings, and the chamber wall of described lumen 12 is provided with heat medium import 4 and heat medium outlet 5.The chamber wall of described cavity of resorption 13 is provided with safety return-flow mouth 3, is sealed and installed with the safety return-flow pipe 8 with epicoele 11 and cavity of resorption 13 connections between described upper spacer 6 and the lower clapboard 7.
